How to get a non-reactive copy of vue data other than via JSON.parse(JSON.stringify)?

Question

JavaScript

Now, when clicked, an editing window opens, when confirmed, the data element is overwritten. So that when editing in the window the properties of the edited object itself do not change, I had to make a copy via JSON.

the example is spherical in a vacuum, don't talk about selecting a window into a component, especially since when passing a reactive object through props, everything works the same way.
